Socket.IO flashsocket security sandbox error - socket.io

Question

I have been playing around with node.js and socket.io for the past few days. Everything works fine on my local machine (windows using iss for a webserver), but when uploading it to my remote server (ubuntu box), I get security errors.
[trace] Warning: Failed to load policy file from http://localhost:8000/crossdomain.xml
[trace] *** Security Sandbox Violation ***
[trace] Connection to http://localhost:8000/socket.io/1/ halted - not permitted from http://****/virtualcinema/VirtualCinema.swf
[trace] Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: http://****/virtualcinema/VirtualCinema.swf cannot load data from http://localhost:8000/socket.io/1/.
The AS3 code it's erroring on is:
Security.loadPolicyFile("xmlsocket://localhost:10843");
socket = new FlashSocket("localhost:8000");
The policy file is being served correctly on port 10843 and I can receive the policy file fine at http://**:10843/ in my browser. Why is it trying to load the policy file on port 8000. That warning does not appear on my local build.
The socket.io code:
socket = io.listen(8000);
socket.configure(function()
{
socket.set("transports", ["flashsocket"]);
socket.set("log level", 2);
});
I'm confused as to why it gets resolved fine when I test it on a localmachine but not on a remote one. Any help would be much appreciated :)
The crossdomain.xml I am using:
<cross-domain-policy>
<allow-access-from domain="*" to-ports="*"/>
</cross-domain-policy>

Answer 1

Fixed. I changed it from pointing to localhost to my servers externalIP.
I had tried this before, but unfortunately the server had cached my swf file and I did not realise it was fixed.
Security.loadPolicyFile("xmlsocket://****.com:10843");
socket = new FlashSocket("****.com:8000");
